I just bought a 2000 XJ 4.0. I am looking on ebay for 4 hole injectors. Some sellers are offering 19lb while others are offering 24lb for the same vehicle..

which one should I get?


I found an old thread on this forum but I don't know how accurate this info is..
the following is a list of the injectors used on the 4.0L since 1987 along with their rated static flow:

Model Year, ...Part #, ......Colour, .....Fuel Pressure, ...Static Flow,
'87-'90, ........53003956, ...Black, ........39psi, .................18.6lb/hr
'91-'93, ........33007127, ...Brown, .......39psi, .................21.0lb/hr
'94-'95, ........53030343, ...Tan, ...........39psi, .................21.0lb/hr
'96-'99, ........53030778, ...Grey, .........49psi, .................23.2lb/hr
'00-'01, ........04854181, ...Blue tip, .....49psi, .................22.5lb/hr

That list is the stock injector flow rates/psi.

For a 2000 you want 784's.
